In order to prevent the, stutng box'rom becoming unduly heated the sameis constructedas follows: R, Rl

The water i is prevented from passingdirectly from the inlet.Y r to the outlett but is compelled to passback'and forth lengthwise oi the water jackets R, Rl for obtaining thefull cooling effect thereof bystopping the water jackets in the upperand lowerbody sections short ofthe joint Y between the body sec-tionsand only v-connectingt them on one side atthe front ends thereof by a.transverse passagen. The; latter crosses the joint between the bodysections and is formed in -a lateral extension or enlargement V formedon the adjacent part ofthe body. vThe v inward pressure against .theperiphery `ofthe `rod .andA f prevent leakage between the rings and ,therod.Vv The sections of the)body are now applied-to the rod in suchposition that their internal grooyes receive the packing rings afterwhich the body sections aresecured toeach other and 'to the adjacent'cylinder head. Thesoft packing is nowplaced in the pocket o of thevbody sections, the gland P is engaged with the soft packing and theclamping nut Q is appliedto'the body and gland.'v

It'has been found in practice that the spring ring packing forms anabsolutely tight joint around the piston rod which effectually preventsleakagey past the same. The gland packing can therefore be dispensed'chambers having'a water inlet and the the ring packing as it affords anadditional security, soV

lwith but it is preierable to' use the same in' addition to g that therings should become broken or leak the gland l packing can be utilizedtorprevent leakage until the sing peeking is repaired. it is wu imm thata' spring ring packing is the most durable and reliable but so far thesame has only been used on the periphery of pistons and'the like to forma tight joint between the same and the cylinders in which the pistonsreciprocate; By dif. l

f l claim as my invention: -v

1. A stung box comprising a tubular body having two semi-cyiindricalsections which are adapted to receive a' movable rod between them,eachof said sections containr ing a semi-cylindrical waterk jacket orchamber' which is independent of and unconnectedgwjith the water jacketor chamber -oi `thev other section;4 except at' one point :it which saidjackets or chambers: communicate with each other by means of n passage,and fone o f said jackets or other a water ont4 let, substantially asset forth. I

2. -A stufug box comprising a tubular body having two semicyiindricalsectionslwhichxare adapted to receive a movable rod between them, eachof. said sections containing a semi-cylindrical water jacket or chamberwhich is independent of and unconnected with the water jacket or chambero the other section except at corresponding ends thereof where thesametare connected by a passage formed ima lateral enlargement of thebodysections and extend 'ing aci-oss' the joint between the sections,and said jackets A or chambers being provided at their-"correspondingoppo site ends with a walter inlet-and a waterbutlet, respecn tively;substantially as set forth. l Witness my hand this 15th day of April,1906.
